Back to original languageAbout Xavier
I turn your product questions into actionable insights. Specializing in user testing, MVP validation, and product strategy.
From idea to launch: I unlock what your users *really* think.
For 12 years, I've led hundreds of qualitative and quantitative studies for product, design, and strategy teams (fintech, e-commerce, SaaS). My approach: less theory, more concrete answers.
What I do (and what changes):
- **User Testing & Validation**: I test your prototypes with real users to validate (or invalidate!) your hypotheses before costly builds.
- **Product Insights**: You get prioritized, actionable recommendations, not a dusty PDF report.
- **De-risking**: I help you identify the friction points killing your acquisition/retention before they cost you dearly.
- **Team Mentoring**: I train your PMs and designers to conduct their own user research (autonomy = long-term gain).
Why choose a user researcher instead of doing it yourself?Because unconscious bias is real, and proven frameworks can save months of development. I bring structure + speed + objectivity.
I excel at:
- MVP validation and product-market fit
- Qualitative vs. quantitative A/B testing
- User onboarding strategy
- Initial discovery (discovery sprints)
- Post-launch studies (NPS, churn analysis)
My style:autonomous, organized, and direct. No fluff. You pay for expert time and clear answers.
Bonus:Anthropology (my background) = I understand the "why" behind user behaviors, not just the "what".
Ready to validate your product or revamp your user strategy? Let's go.
